C5 WH - Ishtar, VNI, Domi, or Tengu?

Spent an hour or so checking out youtube multiboxing videos to snag some ideas on reconfiguring my UI using videofx/clickbars and I ran across a video Mosg2 uploaded. While it is a larger scale operation than I'm considering or what this discussion has circled around, the UI configuration is one of the better ones for PvE. Pretty compact UI, great use of broadcasting, and a clear explanation of what's going on.

That is a great UI and has inspired me to improve my own

There's one part I don't understand and could do with a pointer... when ship X needs armor reps, he appears to just click on the videofeed of that ship's shield/armour display and it sends a fleet "need armor" broadcast which the logi can then use to target and rep.

How is the act of clicking on the VFX generating a fleet broadcast - i know you can set an Eve shortcut for 'need armor' so I presume it's generating that key but I don't know how.

Update... I've just watched it again and he actually exlpains it just after 2m in... invisible clickbars... so time to look into that!
